How to Find Prime Factorization: 14 Steps (with Pictures)

WebMar 19, 2024 · One thing we can observe is if n is prime, then we must return n(1 step to copy, n-1 steps to paste) since no other way to do it. From that observation, let's say n = 15 = 3 * 5, then number of steps is 3 + 1(copy) + 4( 4 pastes),... So just get all the prime factor of n and sum them up.
